C.	REVENUE RECOGNITION

Earnings on construction contracts are reflected in operations using percentage-of-completion accounting, under either cost to cost or units of delivery methods, depending on the nature of the business at individual operations. Under percentage-of-completion using the cost to cost method, revenues and related earnings on construction contracts are measured by the relationships of actual costs incurred related to the total estimated costs. Under percentage-of-completion using the units of delivery method, revenues and related earnings on construction contracts are measured by the relationships of actual units produced related to the total number of units. Revisions in earnings estimates on the construction contracts are recorded in the accounting period in which the basis for such revisions becomes known. Projected losses on individual contracts are charged to operations in their entirety when such losses become apparent.

The following table presents the balances of percentage-of-completion accounts which are included in "Other current assets" and "Accrued liabilities: Other", respectively (in thousands):
